Some years ago I tried my hand at stained glass. (don’t ask the outcome). The other day I was working on a MPU 100 that was pretty badly corroded along the bottom. I thought about using some copper tape used for stained glass. The stuff sticks pretty good. When I used it on glass I just cut the overlap and let the small pieces fall on the concrete floor. The pieces stuck so well to the floor that I had to scrape it off. The down side is the smallest I can find is 5/32 inch – too big for most traces but should work for larger ground traces.
Anyone ever use this stuff?
